I wanted to personally thank you for recommending the right microscopes for our classroom. I am so grateful for your advice.  We were about to order the wrong microscopes when you guided me toward a less expensive model, but correct model. As it turned out, you were right, it was the perfect microscope for my kids! It is reassuring to know you were there to help even when it wasn’t really in your benefit to do so. Thank you so much for your honesty and help.
